Abstract

Gamma rays induced high rate in blackgram photosynthesis and total chlorophyll content in parents and Fi hybrid. Chlorophyll a and b was maximum in hybrid followed by Vamban I and Co 5. The ratio of chlorophyll a/b, showed a positive trend during mutagenesis, however declined at higher doses. In both parents and hybrid, the rate of respiration gradually increased, while flagging subsequently.

Keywords: Gamma rays, photosynthesis, chlorophyll, respiration, blackgram
